[Gunshot wounds of low urinary tract in period of security crisis at the Sominé Dolo Hospital of Mopti (Mali): Epidemiological and diagnostic aspects]. / Blessures par arme à feu du bas appareil urinaire en période de crise sécuritaire à l'hôpital Sominé Dolo de Mopti (Mali) : aspects épidémiologiques et diagnostiques.

INTRODUCTION: Firearm injuries to the lower urinary tract are injuries resulting from an energy transfer from a projectile fired by a firearm or a blast from a firearm, to the bladder, prostate, urethra and terminal ureter. Our objective was to describe the epidemiological and diagnostic aspects in the context of a security crisis. PATIENTS AND METHOD: This was a descriptive cross-sectional study of lower urinary tract firearm injuries at Sominé Dolo Hospital in Mopti from January 2017 to December 2021. RESULTS: In five years, 29 traumas of the lower urinary tract have been collected, about 6 cases per year. The mean age of patients was 27.48 years, the sex ratio was 13.5/1. The main circumstances of occurrence were intercommunal violence 51.72 %, war wounds 31.03 %. Injuries were inflicted by rifles in 62.1 % and improvised explosive devices in 37.9 %. The main modes of discovery were acute urine retention, hematuria and penoscrotal wounds respectively in 31.03 %, 20.69 %, 17.24 %. The organs affected were the urethra in 58.62 %, the bladder, 37.93 %, the prostate 3.45 %. Associated non-urological lesions present in 68.96 % (n=20) were dominated by intestinal lesions and pelvic fractures. CONCLUSION: Firearm injuries to the lower urinary tract are rare despite the context of the security crisis. They affect young men, are mostly linked to intercommunal violence, and are dominated by urethral and bladder injuries.

GAYET WERNICKE'S ENCEPHALOPATHY AFTER COVID-19 IN ELDERLY SUBJECTS IN TROPICAL ENVIRONMENTS: STUDY OF SIX (6) OBSERVATIONS IN CONAKRY.

In sub-Saharan Africa, the COVID-19 pandemic has caused severe malnutrition in elderly populations with the appearance of vitamin deficiencies, in particular thiamine responsible for Gayet Wernicke's encephalopathy (EGW). We present a series of six (6) patients hospitalized in the Neurology Department of the CHU Ignace Deen for the management of a brain syndrome with vigilance disorders after recovery from COVID-19, including oculomotor disorders, motor incoordination on a course of severe weight loss. The six patients underwent an evaluation of malnutrition by determining the WHO body mass index, the Detsky index, the serum albumin assay, the thiamine assay and a neuroradiological assessment (MRI) and an electroencephalogram (EEG) examination although this does not seem necessary for diagnosis. Study of nutritional status: weight loss greater than 5%, patients in Desky group B and C, plasma albumin<30 g/l, lowered thiamine and MRI neuroradiological data: by the existence of hypersignals in certain regions of the neocortex, certain gray nuclei, the mammillary bodies the thalamic nuclei close to the wall of the 3rd ventricle and the regions bordering the 4th ventricle sign Gayet Wernicke's encephalopathy syndrome. This study shows a stereotyped clinical, biological, neuroradiological and evolutionary profile of Gayet Wernicke's encephalopathy in elderly subjects recovered from Covid-19 with proven malnutrition. These results are useful for the therapeutic and prognostic discussion.

[Treatment outcome, survival and their risk factors among new tuberculosis patients co-infected with HIV during the Ebola outbreak in Conakry]. / L'issue du traitement, la survie et ses facteurs de risque chez les nouveaux tuberculeux co-infectés par le VIH pendant l'épidémie d'Ebola à Conakry.

BACKGROUND: Mortality among TB/HIV co-infected patients remains high in Africa. The study aimed to estimate survival and associated factors in a cohort of TB/HIV co-infected patients who started tuberculosis treatment during the Ebola outbreak in Conakry, Guinea. METHODS: A prospective cohort study was conducted from April 2014 to December 2015. TB patients with HIV co-infection were enrolled at the University Hospital of Conakry. Survival and risk factors were analyzed according to Kaplan-Meier's method, log-rank test and Cox's regression. RESULTS: Data from 573 patients were analyzed. From these, 86 (15.0%) died before the end of treatment, 52% occurring within eight weeks of treatment onset. Survival at 4, 12 and 24 weeks after the beginning of the TB treatment was 92%, 86% and 83%, respectively. Independent risk factors associated with death were in the cell CD4 <200 cells/mm3 [adjusted hazard ratio (AHR): 2.25; 95% CI (confidence intervals): 1.16-4.37], opportunistic infections other than TB [AHR: 2.89; 95% CI: 1.39-6.02], and comorbidities [AHR: 4.12; 95% CI: 2.10-8.10]. An increase of one unit in hemoglobin [AHR: 0.81; 95% CI: 0.75-0.91] was protective of death. CONCLUSION: TB/HIV co-infected patients had a higher fatality rate during treatment of tuberculosis. Prevention of opportunistic infections, anemia and proper management of tuberculosis treatment in early comorbidities may improve survival for TB/HIV co-infected patients in restoring immune function.

Ischemic strokes revealing neurosyphilis: Study of six (6) observations at the neurology Department of the University Hospital of Conakry.

Introduction: In sub-Saharan Africa (SSA), stroke is a major public health problem and the etiological aspects are poorly studied and documented because of under-medicalization; the syphilitic etiology is rarely mentioned. Patients and methods: We performed a retrospective study of 472 patients hospitalized for ischemic stroke between 2016 and 2021 in the Neurology Department of the University Hospital of Conakry, confirmed by neuroradiological explorations (brain CT, MRI-Angio) and a biological workup including VDRL-TPHA serological reactions in blood and CSF. Results: Syphilitic etiology was retained for six (6) patients (4 men and 2 women) with a mean age of 43 years (extremes 36 and 49 years). The clinical picture was dominated by carotid syndromes: superficial and deep sylvian syndrome, anterior cerebral artery syndrome and vertebro-basilar syndromes and one case of lacunar syndrome.The diagnosis was based on the positivity of serological reactions (VDRL-TPHA) in blood and cerebrospinal fluid (CSF) and the presence of a predominantly lymphocytic hypercellularity and a hyperproteinorachy in the CSF in the absence of any other etiology. Conclusion: These neurological vascular syndromes consecutive to a cerebral treponematous attack are often the result of a still poorly conducted management of primary and secondary syphilis in our country.

[Intrapartum obstetrical transfers: sociodemographic, clinical and prognosistic aspects in Conakry, Guinea]. / Evacuations obstétricales intrapartum: aspects sociodémographique, clinique et pronostique à Conakry, Guinée.

The objectives of this descriptive prospective study were to determine the frequency of intrapartum obstetrical transfers, assess the sociodemographic profile of parturients requiring transfer, describe transfer modalities, and assess maternal and newborn outcomes. Study included all patients requiring intrepartum obstetrical transfer to the Ignace Deen University Hospital Gynecology Obstetrics Clinic in Conakry, Guinea from August 1st, 2009 to July 31st, 2010. Out of 3122 deliveries during the study period, intrapartum transfer was required in 220 cases, i.e. 7.05%. Mean patient age was 23.2 years (range, 14 to 44). The risk for intrapartum transfer was higher among multiparous or nulliparous women (incidence, 8.79%) and adolescents (incidence, 10%). Patients requiring transfer were mainly housewives (60%) and uneducated women (57.27%). Most had had an insufficient number (<4) of antenatal examinations (76.36%) and had been examined at peripheral maternity units (62.73%). In 175 cases (79.54%), patients were transferred by taxi. In 191 patients, treatment required surgery including 130 caesarian sections. There were 12 maternal deaths (5.45%) and 45 neonatal deaths out of 242 newborns including 22 twin deliveries (18.59%). Further work is necessary to improve referral and transfer at all levels of the health pyramid.

[Investigation of epidemiology of neurotrauma in the Republic of Guinea].

The paper focuses on analysis of incidence of neurotrauma in economically underdeveloped country such as Republic of Guinea. It is found that leading etiology of central nervous system injuries are road accidents and indoor traumatism. Investigation of system of medical care revealed its poor condition and severe defects which prevent practical application of evidence-based recommendations for management of traumatic brain injury in underdeveloped countries including Republic of Guinea. Development of multiplanar strategy of control of neurotrauma is required which can be achieved only in case of massive governmental and international aid.

[Management of pre-term labor: use of nifedipine in Conakry, Guinea]. / Menaces d'accouchement prématuré: utilisation de la nifédipine à Conakry, Guinée.

This purpose of this prospective and descriptive study was to evaluate the utility of a calcium-channel inhibitor, i.e. nifedipine, for management of preterm labor in our work setting in terms of safety and cost-effectiveness in comparison with betamimetics classically used for this indication. Study was carried out over a six-month period in the department of Gynecology-Obstetrics Department of Ignace Deen National Hospital in Conakry, Guinea. Pregnant women meeting the following criteria were included: 28 to 33 weeks of amenorrhea, six days of hospitalization either for preterm labor or for another diagnosis that was associated with the occurrence of preterm labor during hospitalization, and absence of contraindications for tocolysis using nifedipine. A total of 42 women were included. Pregnancy was extended for more than 48 hours after the first dose of nifedipine in 86.8% of cases. Administration of nifedipine failed in 5 cases including one case in which it was necessary to change the tocolytic and 4 cases in which delivery occurred less than 48 hours after the first dose of nifedipine. In 68% of cases, 90 mg of nifedipine were sufficient to stop uterine contractions within 48 hours. In 39.5% of cases, no side effects were observed. Adverse effects in the other cases were dizziness (39.5%) and headache (18.4%). The mean term of delivery was 36 weeks +/- 5 days of amenorrhea with a mean extension of 6.2 weeks. Apgar score was low in 30.5% of the newborns and normal in 69.5%. One newborn (2.8%) died. The results of this study indicate that nifedipine is an effective, economical and safe drug for tocolysis and that it can be used as an alternative to betamimetis in countries with limited resources. An information campaign is needed to promote use of nifedipine as a tocolytic in obstetrical facilities of our country.

[Management of ectopic pregnancy in Conakry, Guinea]. / Prise en charge de la grossesse extra utérine à Conakry (Guinée).

Ectopic pregnancy is one of the most frequent hemorrhagic emergencies encountered in gynecology and obstetrics. The purpose of this 16-month descriptive prospective study at the Ignace Deen Gynecology-Obstetric clinic at Conakry University Hospital in Guinea was to assess diagnostic techniques and therapeutic attitudes regarding ectopic pregnancy in a low-resource setting. The frequency of ectopic pregnancy was 1.4%. Mean patient age was 28.9 years. Ectopic pregnancy was often observed at the second or third pregnancy (47.1%) in women who were giving birth for the second or third time (36.0%) and had a history of sexually transmitted infections (88.2%) or abortions (43.1%). Most women had no schooling (60.8 %), were poor and lived in a marital home (86.3%). Presenting symptoms included the classic triad of amenorrhea (98.0%), abdominopelvic pain (92.2%), and vaginal bleeding (62.7%). Definitive diagnosis was achieved by ultrasound examination in 76.6% of cases and by puncture of the Douglas pouch in 84%. The most frequent site of ectopic pregnancy was the ampulla of the uterine tube (66.9%). Abdominal and ovarian pregnancy was observed in 3 and 4 of the 51 cases respectively. Surgical management was performed in all cases. The most frequent procedure was salpingectomy (80.3%). Proper treatment of sexually transmitted infections (STI), start-up of post-abortion care facilities, and provision of information during early consultation at the first signs of pregnancy would help reduce the frequency and improve the prognosis of ectopic pregnancy.

[The Ileal Neobladder With The Hautmann Technic At The Urology Depatment Of University Hospital Pr. Bocar S. SALL Of Kati]. / Le Remplacement De Vessie Selon La Technique De Hautmann Au Service D'Urologie Du Chu Pr. Bocar S. SALL De Kati.

Radical cystectomy is the standard treatment for bladder tumors infiltrating the bladder muscle, for patients who have tumors without invasion of neighboring organs and without metastasis. After radical cystectomy, the urinary diversion is a challenge for any urologist. Ileal neo bladder is a rare surgery in our country. The ileal neo bladder is recommended in these patients. We report a case of ileal neo bladder in a 42-year-old woman with a bladder tumor. We discuss the clinical, diagnostic and therapeutic aspects.

La cystectomie totale constitue le traitement de référence des tumeurs de vessie infiltrant le muscle vésical, pour les patients qui ont une tumeur sans envahissement des organes voisins et sans métastase. Après la cystectomie, la dérivation des urines est un challenge pour tout urologue. Le remplacement de vessie est un geste rarement réalisé dans notre pays. Un remplacement de vessie par l'intestin est recommandé chez ces patients. Nous rapportons un cas de remplacement de vessie chez une femme de 42 ans ayant une tumeur de vessie. Nous discutons les aspects cliniques, diagnostiques et thérapeutiques.

Prevalence, management and ethnobotanical investigation of hypertension in two Guinean urban districts.

ETHNOPHARMACOLOGICAL RELEVANCE: Hypertension is an important public health challenge in low- and middle-income countries, and in many African countries including Guinea medicinal plants are still widely used for its treatment. MATERIALS AND METHODS: The objective of this study was to determine the prevalence of hypertension in two Guinean urban districts (Pounthioun and Dowsare), to describe its management and to collect information on traditional herbal remedies. A total of 316 participants entered the study, 28.2% (89/316) men and 71.8% (227/316) women. Of these, 181 were from Dowsare (50 men and 131 women) and 135 from Pounthioun (39 men and 96 women). The mean age of subjects was 40.8 ±â€¯14.0 years (range18 - 88years), while the majority of subjects (63.3% or 200/316) were 45-74 years old. RESULTS: The overall prevalence of hypertension was 44.9% (142/316): 46.4% (84/181) from Dowsare and 43.0% (58/135) from Pounthioun. Ethnobotanical investigations among hypertensive patients led to the collection of 15 plant species, among which Hymenocardia acida leaves and Uapaca togoensis stem bark were the most cited. Phytochemical investigation of these two plant species led to the isolation and identification of isovitexin and isoorientin from H. acida, and betulinic acid and lupeol from U. togoensis. CONCLUSION: The presence of these constituents in Hymenocardia acida leaves and Uapaca togoensis stem bark may at least in part support their traditional use against hypertension in Guinea.

[Patients' satisfaction survey after tranvesical prostatectomy in the urology department of Gabriel Touré University Hospital]. / Evaluation de la Satisfaction des Patients Apres Adenomectomie Transvesicale de la Prosate dans le Service D'Urologie du Chugabriel Toure.

AIM: This study was aimed to evaluate patients' satisfaction with tranvesical prostatectomy in the Urology department of University Hospital Gabriel Touré according to the (International Prostate Symptoms Score (IPSS) and the quality of life scores. PATIENTS AND METHODS: We conducted a prospective descriptive study over a 12-month period including a consecutive cohort of patients who had transvesical prostatectomy. Each patient was evaluated before and six weeks after the surgery. We used the IPSS as an assessment tool, supplemented by the Quality of Life (SQ) questionnaire. RESULTS: One hundred and thirteen (113) patients aged 71 ± 8 years old on average were evaluated. The mean duration of symptoms associated with benign prostatic hyperplasia was 19 months and 17% of patients had a mechanical complication. All patients had either moderate or severe lower urinary tract symptoms preoperatively, while 99% of them had an IPSS score <8 postoperatively. CONCLUSION: Transvesical prostatectomy allows an important improvement of the IPSS score of the patients and their satisfaction about their quality of life.

Les patients étaient tous évalués avant l'intervention chirurgicale et 6 semaines après. Nous avons utilisé l'IPSS comme outil d'évaluation, complété par la question sur la qualité de vie. RÉSULTATS: Cent treize patients d'âge moyen de 71 ± 8ans ont été évalués. La durée moyenne d'évolution des symptômes liés à l'hypertrophie bénigne de la prostate était de 19 mois et 17 % des patients présentaient une complication mécanique. Tous les patients présentaient des symptômes modérés ou sévères du bas appareil urinaire en préopératoire tandis qu'en postopératoire 99% des patients avaient un score IPSS inférieur à 8. CONCLUSION: l'adénomectomie transvésicale de la prostate permet une amélioration du score IPSS et celui de la qualité de vie des patients avec une importante satisfaction des patients.

[Urological Complications of Pelvic Surgery at Point-G Hospital, About 23 Cases]. / Les Complications Urologiques Liees a la Chirurgie Pelvienne au CHU du Point-G, a Proposde 23 cas.

INTRODUCTION: Bladder and ureteral lesions are the most common urologic complications occurring during pelvic surgery with 1% and 0.5% to 3%, respectively. These lesions are rarely recognized intraoperatively and pose a major problem to urologists, gynecologists, and general surgeons. OBJECTIVE: To study the factors favoring urologic complications following pelvic surgery at the University Hospital Point-G. PATIENTS AND METHOD: We conducted a retrospective study at the University Hospital Point-G between 2006 and 2015. It involved 23 patients with a whole urological lesion following pelvic surgery. These patients underwent a clinical and para-clinical examination (intravenous urography, methylene blue test) to confirm the urological lesion and to determine its management. RESULTS: The average age of our patients was 32.00 years with extremes of 18 and 40 years old. The leakage of urine was found in 82.6% (19/23). Interventions that caused urologic injury were: caesarean section 52.2% (12/23), hysterectomy 30.4% (7/23), as well as a caesarean section and hysterectomy 17.4% (4/23). Methylene blue was performed in 19 patients, it was positive in 52.2% (12/23) and intravenous urography (IVU) in 7 patients. The lesions encountered were: retrotrigonal fistula vesico-vaginal 10 cases, vesico-vaginal fistula under trigonal 2 cases, uretero-vaginal fistula 7 cases, and bilateral ureteral ligation 4 cases. Fistulorraphy was performed in 52.2% followed by direct ureterovesical reimplantation. The postoperative outcome was satisfactory in 100% of cases with obtaining a good bladder tightness. The average duration of hospitalization was 12 days (+/- 4 days). CONCLUSION: Pelvic surgery results in urological injuries. Caesarean section and hysterectomy are contributing factors. Vesico-vaginal fistula or ureteral lesions are common.

INTRODUCTION: Les lésions vésicale et urétérale constituent les complications urologiques les plus fréquentes survenant au décours d'une chirurgie pelvienne soit respectivement 1 à 4% et 0,5 à 3% [6,7]. Ces lésions sont rarement reconnues en peropératoire et posent un problème important auquel sont confrontés les urologues, les gynécologues, les chirurgiens généralistes. OBJECTIF: Etudier les facteurs favorisants les complications urologiques consécutives à la chirurgie pelvienne au CHU du Point-G. PATIENTES ET MÉTHODE: Il s'agissait d'une étude rétrospective réalisée au CHU du Point-G entre 2006 et 2015. Elle a concerné 23 patientes présentant toute une lésion urologique au décours d'une chirurgie pelvienne. Ces patientes ont subi un examen clinique et para cliniques (Urographie intra veineuse; le test au bleu de méthylène) dans le but de confirmer la lésion urologique et d'en déterminer la prise en charge. RÉSULTATS: l'âge moyen de nos patientes était de 32,00 ans avec des extrêmes allant de 18 à 40 ans. La fuite d'urine était retrouvée chez 82,6% (19/23). Les interventions pourvoyeuses de lésions urologique étaient : la césarienne 52, 2% (12/23), l'hystérectomie 30, 4% (7/23), une association césarienne et hystérectomie 17,4 % (4/23). Le test au bleu de méthylène a été réalisé chez 19 patientes, il a été positif dans 12 cas soit 52,2 % et l'UIV chez 7 patientes. Les lésions rencontrées étaient : la fistule vésico-vaginale retro trigonale 10 cas, la fistule vésico-vaginale sous trigonale 2 cas, la fistule urétéro-vaginale 7 cas, et la ligature urétérale bilatérale 4 cas. La fistulorraphie a été effectuée dans 52,2 % suivie de la réimplantation urétéro-vésicale directe. Les suites opératoires étaient satisfaisantes dans 100% des cas avec l'obtention d'une bonne étanchéité vésicale. La durée moyenne d'hospitalisation était de 12 jours (+/− 4 jours). CONCLUSION: La chirurgie pelvienne est pourvoyeuse de lésions urologiques. La césarienne et l'hystérectomie sont des facteurs favorisants. Les fistules vésico-vaginales ou des lésions urétérales sont fréquentes.

Reduction in exposure to carcinogenic aflatoxins by postharvest intervention measures in west Africa: a community-based intervention study.

BACKGROUND: Aflatoxins are fungal metabolites that frequently contaminate staple foods in much of sub-Saharan Africa, and are associated with increased risk of liver cancer and impaired growth in young children. We aimed to assess whether postharvest measures to restrict aflatoxin contamination of groundnut crops could reduce exposure in west African villages. METHODS: We undertook an intervention study at subsistence farms in the lower Kindia region of Guinea. Farms from 20 villages were included, ten of which implemented a package of postharvest measures to restrict aflatoxin contamination of the groundnut crop; ten controls followed usual postharvest practices. We measured the concentrations of blood aflatoxin-albumin adducts from 600 people immediately after harvest and at 3 months and 5 months postharvest to monitor the effectiveness of the intervention. FINDINGS: In control villages mean aflatoxin-albumin concentration increased postharvest (from 5.5 pg/mg [95% CI 4.7-6.1] immediately after harvest to 18.7 pg/mg [17.0-20.6] 5 months later). By contrast, mean aflatoxin-albumin concentration in intervention villages after 5 months of groundnut storage was much the same as that immediately postharvest (7.2 pg/mg [6.2-8.4] vs 8.0 pg/mg [7.0-9.2]). At 5 months, mean adduct concentration in intervention villages was less than 50% of that in control villages (8.0 pg/mg [7.2-9.2] vs 18.7 pg/mg [17.0-20.6], p<0.0001). About a third of the number of people had non-detectable aflatoxin-albumin concentrations at harvest. At 5 months, five (2%) people in the control villages had non-detectable adduct concentrations compared with 47 (20%) of those in the intervention group (p<0.0001). Mean concentrations of aflatoxin B1 in groundnuts in household stores in intervention and control villages were consistent with measurements of aflatoxin-albumin adducts. INTERPRETATION: Use of low-technology approaches at the subsistence-farm level in sub-Saharan Africa could substantially reduce the disease burden caused by aflatoxin exposure.

Ethnomedical and ethnobotanical investigations on the response capacities of Guinean traditional health practioners in the management of outbreaks of infectious diseases: The case of the Ebola virus epidemic.

ETHNOPHARMACOLOGICAL RELEVANCE: The recent outbreak of Ebola virus infections has mostly remained confined to the West African countries Guinea-Conakry, Sierra-Leone and Liberia. Due to intense national and international mobilizations, a significant reduction in Ebola virus transmission has been recorded. While international efforts focus on new vaccines, medicines and diagnostics, no coherent national or international approach exists to integrate the potential of the traditional health practitioners (THPs) in the management of infectious diseases epidemics. Nevertheless, the first contact of most of the Ebola infected patients is with the THPs since the symptoms are similar to those of common traditionally treated diseases or symptoms such as malaria, hemorrhagic syndrome, typhoid or other gastrointestinal diseases, fever and vomiting. MATERIALS AND METHODS: In an ethnomedical survey conducted in the 4 main Guinean regions contacts were established with a total of 113 THPs. The socio-demographic characteristics, the professional status and the traditional perception of Ebola Virus Disease (EVD) were recorded. RESULTS: The traditional treatment of the main symptoms was based on 47 vegetal recipes which were focused on the treatment of diarrhea (22 recipes), fever (22 recipes), vomiting (2 recipes), external antiseptic (2 recipes), hemorrhagic syndrome (2 recipes), convulsion and dysentery (one recipe each). An ethnobotanical survey led to the collection of 54 plant species from which 44 identified belonging to 26 families. The most represented families were Euphorbiaceae, Caesalpiniaceae and Rubiaceae. Literature data on the twelve most cited plant species tends to corroborate their traditional use and to highlight their pharmacological potential. CONCLUSIONS: It is worth to document all available knowledge on the traditional management of EVD-like symptoms in order to evaluate systematically the anti-Ebola potential of Guinean plant species.

[Study of factors influencing clinical outcomes of obstetric urogenital fistula surgery at the Point G University Hospital of Bamako, Mali]. / Etude des facteurs influençant les resultats clinique de la chirurgie de la fistule uro-genitale obstetricale au CHU de l'Hopital du point G Bamako Mali.

The aim of this study was to identify factors influencing the clinical outcomes of surgery of obstetric urogenital genital fistula. This was a cross sectional study, which focused on factors influencing results in the treatment of urogenital fistula, from January 2011 to January 2012 at the urology department of the Point-G University Hospital. This study involved 115 patients suffering from urogenital fistula. Cure of urogenital fistula accounted for 17% of the bloc's activities. Closure of the fistula was achieved in 68.7% of cases. This result was influenced by certain factors. Including factors related to condition of the tissue peri-fistula (good trophic tissue, or fibrosis peri-fistula). Fistulas operated primarily peri-sinus tissue remodeling were closed in 71.42% of cases. Factors related to the patient and care: those carried out for the first time have a success rate of 68.42%, only 47.62% of success in patients who presented after five years. Factors related to clinicopathological seat: fistula vesicovaginal septum and cervical-vaginal urethrovaginal reported a success rate of 76.92%. Care-related factors include: the experience of the surgeon, surgeons of the urology service have a 76.19% success rate against 25% from other surgeons. The incision fistula was related to the clinicopathological seat, so the trigonal-vaginal fistulas and uretero addressed by the upper route have been successful in 85%. In addition to these factors the postoperative follow-up, the instruments, the suture thread, the operating table, and the lighting in the room have also improved the results.

Le but de cette étude était d'identifier les facteurs influençant les résultats cliniques de la chirurgie de la fistule uro- génitale obstétricale. Il s'agissait d'une étude transversale, qui a porté sur les facteurs influençant les résultats dans la prise en charge de fistule uro-génitale, allant du janvier 2011 au janvier 2012 au service d'urologie du CHU du Point-G. Cette étude a concerné 115 patientes souffrantes de fistule uro-génitale. La cure de la fistule uro-génitale a représenté 17 % des activités du bloc. La fermeture de la fistule a été obtenue dans 68,7% des cas. Ce résultat a été influencé par certains facteurs, dont les facteurs liés à l'état du tissu péri-fistuleux (bonne trophicité du tissu, ou fibrose péri-fistuleux). Les fistules opérées avant tout remaniement tissulaire péri-fistuleux ont été fermées dans 71,42 % des cas. Les facteurs liés à la patiente et aux soins : celles opérées pour la première fois ont un taux de réussite de 68,42 %, seulement 47,62 % de succès chez les patientes qui se sont présentées après cinq ans. Les facteurs liés au siège anatomo-clinique : les fistules de la cloison vésico-vaginale et cervico-urétro-vaginale ont occupé un taux de succès de 76,92 %. Les facteurs liés aux soins regroupent : l'expérience du chirurgien, les chirurgiens du service d'urologie contrairement aux autres chirurgiens ont 76,19 % de réussite contre 25%. La voie d'abord de la fistule était en rapport avec le siège anatomo-clinique, ainsi les fistules trigonales et urétéro-vaginales abordées par la voie haute ont été réussies dans 85 %. En plus de ces facteurs le suivi post-opératoire, les instruments, les fils de suture, la table opératoire, l'éclairage de la salle ont améliorée aussi les résultats.

Interactions between hepatitis B virus infection and exposure to aflatoxins in the development of hepatocellular carcinoma: a molecular epidemiological approach.

Aflatoxins and hepatitis B virus (HBV) are major risk factors for hepatocellular carcinoma (HCC) in high incidence areas for this cancer, namely southeast Asia and parts of Africa. There is evidence from both epidemiological studies and animal models that the two factors can act synergistically to increase the risk of HCC. The cellular and molecular mechanism of the interaction between these two factors is as yet undefined. However, one possible mechanism attested to by studies in HBV transgenic mice is that chronic liver injury alters the expression of specific carcinogen metabolising enzymes thus modulating the binding of aflatoxin to DNA in hepatocytes. The high levels of aflatoxin exposure which occur in many areas of the world where chronic HBV infection is endemic indicate that measures to reduce aflatoxin exposure would contribute to reducing HCC incidence. In preliminary studies, Guinea-Conakry have established baseline data for the implementation of a community-based intervention study to evaluate the effectiveness of improved post-harvest processing and storage of the groundnut crop, a major source of aflatoxins. Aflatoxin-albumin adducts were measured in 423 sera from individuals living in the four natural geographic zones of Guinea. More than 95% of the serum samples were positive for this biomarker and highest exposures were found in Lower Guinea where groundnuts are consumed as a dietary staple. Variations in mean levels between villages within a geographic region did not vary greatly. HBV infection was endemic in all regions with an overall prevalence of 16.7% chronic carriers. Thus in this population both HBV vaccination and reduction in aflatoxin exposure would be beneficial in decreasing morbidity and mortality from liver disease.

[Maternal mortality at the University Hospital Center of Donka (Conakry, Guinea)]. / Etude de la mortalité maternelle au CHU de Donka (Conakry, Guinée).

We report the first results of the analysis of maternal mortality at the university hospital of Donka, Conakry, Guinée. This paper details the mortality rate [12.47/1,000] in a consultant service which has very limited facilities. It outlines the causes of death, the dramatic circumstances in which the accidents occur and it discusses the notion of responsibility and above all the means to reduce these terrible mortality figures: an increase in primary health care, peripheral obstetrical services, training of health personnel and of traditional birth attendants, as well as education of the population.

[Uterine rupture. Apropos of 155 cases observed in Conakry (Republic of Guinea)]. / Ruptures utérines. A propos de 155 cas observés à Conakry (République de Guinée).

From 155 cases of uterus rupture observed during 5 years at the CHU of Donka (Conakry), the authors are reminding: a) the high frequency of this obstetrical emergency: 0.74% of child births and 12.76% of the extractions by caesarean section: b) the high rate of maternal mortality: 25.16%. They insist on: 1. The important role of some parameters: socio economic conditions, lack of an appropriate infrastructure and of a qualified staff leading to a lack of obstetrical observation, parity, age of pregnant women, way of recruiting.... 2. The necessity to apply a correct supervision of the pregnant women and of delivery by establishing a good system of prenatal examination. The therapeutic problems, including the future of the mother and of the child are discussed, insisting on the necessity of the chirurgical celerity in case of dystocia.

[Serological evidence of Lassa virus circulation in the Republic of Guinea]. / Serologicheskie dokazatel'stva tsirkuliatsii virusa Lassa v Gvineiskoi Respublike.

Seroepidemiological investigations in Guinea were carried out to estimate the areas of Lassa virus circulation. The recombinant protein of Lassa virus nucleocapsid was used as the antigen to analyse blood sera by ELISA. In some regions, from 30 to 54.9% of the population had antibodies to Lassa virus, but in others only 6-7%.

[Epidemiology and prognosis of cervix cancer. Experience of the University Gynecology and Obstetric Clinic Ignace Deen of Conakry in 10 years: 1982-1991]. / Epidémiologie et pronostic du cancer du col de l'utérus. Expérience de la Clinique Universitaire de Gynécologie et d'Obstétrique Ignace Deen de Conakry, en dix ans: 1982-1991.

The cancer of the cervix is a tumor that can be detected at an early stage. Unfortunately, it is still detected lately in our service. Thus, it is the underlying cause of death by gynecological affection. After a preliminary work in 1982 about 35 case histories, the authors undertake a 10 years retrospective study where they showed that: the cancer of the cervix is the primary gynecological cancer (78.7%), it obtains between 25 and 65 years, the most often associated factors are early sex, (28%), poor living conditions (22%), cercivitise (17%), metrorrhagias (24%) and leucorrhoea are the most frequent signs. buding lesions are the dominant macroscopic form (68%) epidermoid carcinoma is the most important histological type, 98.7% cancer cases are detected at advanced stages (T3 and T4), the prognosis is dramatic: most patients die at home. This is a great public health issue the solution of which implies the collective action of decision-markers, health personnel and the communities themselves in order to promote early detection.
